PCM1725U/2K

ADCs/DACs - Special Purpose Overview

The PCM1725U/2K is a stereo audio digital-to-analog converter (DAC) manufactured by Texas Instruments. It features a sigma-delta architecture with 16-bit resolution and supports sampling rates up to 96 kHz. The device operates on a single 5V supply, with voltage ranges from 4.5 V to 5.5 V. It provides two analog outputs and utilizes a serial interface for data input. Key performance metrics include a signal-to-noise ratio of 97 dB and a gain error of +/- 5% FSR. The component is housed in an SOIC-14 package and is rated for operation between -25°C and +85°C.

ADCs/DACs - Special Purpose Feature Summary

• 16-bit resolution with 96 kHz maximum sampling rate
• Serial interface compatibility for digital audio data
• Single 5V power supply operation (4.5 V to 5.5 V)
• 97 dB signal-to-noise ratio (SNR)

ADCs/DACs - Special Purpose Applications

• Stereo audio playback systems
• Home theater receivers
• Portable audio devices

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'U/2K' against official Texas Instruments documentation to confirm packaging details and RoHS compliance status. Check current lifecycle status as older PCM1725 variants may be obsolete or recommended for new design alternatives. Ensure sourcing channels provide valid traceability for electronic components.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a 16-bit stereo DAC with 96 kHz capability is required. Compare SNR and THD+N specifications against higher-resolution alternatives like the PCM1723 if superior dynamic range is needed. Confirm that the serial interface protocol matches the system's microcontroller or DSP requirements.

ADCs/DACs - Special Purpose Part Context

The PCM1725 belongs to the PCM17xx series of audio DACs from Texas Instruments. It serves as a mid-range solution compared to the 24-bit PCM1723 or the integrated codec PCM3002. The 'U' indicates the SOIC-14 package, while '/2K' typically denotes tape and reel packaging quantities.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1723E/2K offers 24-bit resolution and similar form factor but requires verification of pin compatibility. The PCM1742KE/2K provides 24-bit/192 kHz performance but uses an SSOP-16 package. Verify electrical parameters before substitution.
